In addition, the framework provides support for inspecting framework-specific objects at runtime.</p><p>The <a shape="rect" href="debugginginterceptor.html">Debugging Interceptor</a> provides three debugging modes to provide insight into the data behind the page. The <code>xml</code> mode formats relevant framework objects as an XML document. The <code>console</code> mode provides a OGNL command line that accepts entry of runtime expressions, and the <code>browser</code> mode adds an interactive page that display objects from the Value Stack.</p><p>To use the debugging, first be sure that <code>struts.devMode</code> is set to <code>true</code> is enabled through the <a shape="rect" href="strutsproperties.html">struts.properties</a> file or <code>struts.xml</code> file, like:</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
<pre class="brush: xml; gutter: false; theme: Default" style="font-size:12px;">&lt;constant name="struts.devMode" value="true" /&gt;
</pre>
</div></div><p>Then, whenever a page needs debugging, add <code>?debug=xml</code> or <code>?debug=console</code> or <code>?debug=browser</code> to the URL.</p><div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
